ILLINOIS HAND CLIPPER Application filed November 24, 1930. Serial No. 497,774.

My invention relates to hair the like and clipper.

The principal purpose of this inventlon 1s clippers and particularly to a hand operated to provide a novel chpper construction for.

hand clippers whereby the fineness of the cut may be varied at will by the operator without in any way interfering with the smoothness of the operation of the clippers.

More specifically it is a purpose of this invention to provide a hand clipper with a movable stationary blade the position of which may be changed to vary the amount it projects beyond the tip of the movable blade any desired amount.

It is also a purpose of this invention to provide in a clipper of the character described a novel means for guiding the movable blade in its cutting action.

A further and more specific object of the invention is to provide in a clipper of this character an adjustable stationary blade for varying the fineness or closeness of the cut of the clipper and operating means for said adjustable blade which is readily shiftable to make the same accessible for both right and left hand operation without any changes.

I will describe the preferred form of my invention by reference to the accompanying drawings wherein Fig. 1 is a side view of the clipper embodying my invention;

Fig. 2 is a section taken trally through the clipper;

Fig. 3 is a section on the line 3-8 of Fig. 2;

Fig. 4. is a section on the line 4 1 of Fig. 2;

Fig. 5 is a section on the line 55 of Fig. 2;

Fig. 6 is a section on the line 6-6 of Fig. 2;

Fig. 7 is a bottom view of the stationary substantially cenblade of the clipper; and

Fig. 8 is a fragmentary end view showing the manner of guiding the stationary blade. 7

Referring now in detail to the drawings, I show in Fig. 1 an ordinary hand clipper having the handles 10 and 11, one of which the handle 10 is fixed with respect to the clipper body 12 and the other of which is pivotally mounted by means of the sleeve 13 0 upon the pin 14 fixed to the body 12. A suitable spring 15 yieldingly urges the handles apart in a well known manner, and the cutting actionof the clipper is caused by the operation drawing handle 11 toward handle 10 and allowing the spring 15 to then return the handle 11 to its original position. This handle 11 is urged with the operating finger 16 which extends down into the slot 17 in the movable blade 18.

Thus it will be seen that as the handle 11 is moved in the fashion just described, there will be force exerted to move the movable blade 11 across the teeth of the blade 19 to accomplish the cutting.

The. fineness or coarseness of the cut of a hair clipper may be changed, as is well known, by varying the distance which the stationary blade 19 projects beyond the movable blade 18 where the points are sloping as shown. 7 In the common use of'hand clippers, different stationary blades have been used to obtain this variable cut, and in many instances the barber obtains the varying degrees of fineness of cut by keeping at hand several clippers, that is, at least two or three in order that he may obtain close clipping andlonger or coarser clipping.

I find that I can obtain all the adjustments upon a single clipper necessary for fine 0r coarse clipping or anyintermediate length by the utilization of an adjustable stationary blade structure. Adjustable stationary blades are not atthis time broadly new in connection with clippers. There are, however, certain features in the application of a stationary blade to a hand clipper that I believe to be particularly novel and useful.

In the present instance, the stationary blade 19 is held up against the clipper frame 12 by means of a base 20. This base 20 is secured by means of suitable screws such as indicated at 21 and 22 in Fig. 4: to the body 12. The upper surface of the base 20 is provided with a transversely extending cut-out portion 21, and, at the opposite ends of the stationary blade 19, suitable guide bearings indicated at-22 and 23 are formed on the base 20 to cooperate with grooves such as indicated at 24c and 25 in the bottom of the stationary blade. The stationary blade is thus supported at its front end on the base 20 by means of bearings 22 and 22 and at its rear end by means of the bearings 23. The base is, of course, cut away at the rear end to permit endwise sliding of the rearwardly extending tongue portion 26 of the stationary blade which tongue portion carries the groove 25.

The blade moving forward or rearwardly with respect to the movable blade 18', and I provide as'a means of moving'the same a spring lever 27. This lever is pivoted by means of the securing means 28 to the stationary blade 19.

and is bowed intermediate its ends so as to have a tendency to force the end 29 thereof downwardly into the transverse groove 21 of the base 20. Projections 30 and 31 at the end 29 form a fulcrum by means of which swinging movement of the lever 27'ab0ut these ends at the fulcrum will result in moving the stationary blade forward or backward. Suitable upstruck portions such as '32 and 33 on the lever cooperate with suitable notches or grooves provided in the stationary blade to give a latching means to further aid in holding the stationary blade in any adjusted position.

The lever 27, it will be noted, can be turned end for end on the stationary blade from the position shown in Fig. 7 so as to move the operating lug 35 thereon .to eithe'r'end of the stationary lad-e thus making the stationary blade applicable to both right and left hand clippers with the adjusting lever in the most convenient position for the operator of either type. It is well known,'of course, that in a left hand clipper the handles are-so changed that handle 11 for example would be the stationary'handle while handle 10 would be the movable one.

Now in order to insure proper tension between the two blades and also proper holding of the stationary blade in it's bearings, I provide a novel means for supporting and guiding the movable blade. This movable blade is provided with a groove extending directly across the same as indicated for example at 36 in Fig. 6. Fitting in this transverse groove is the depending front'edge portion 37 of the housing 38 which housing or cover is apertured as at 39 to receive the .pin 14; and which has a'rearwardly extending portion 40 which extends down into a notch 41 formed in the base 12 and thus rigidly positions the cover or housing 38. That is to say, pin 14 fits rather snugly in aperture 39, and extension 40 fits rather closely in the notch 41. Thus these two points align the front edge of the cover so that it forms a guide for the movable blade when'the same ismoved back and forth by means of the arms 16 in 'a well known manner A stop pr-ojectio'n42 on the front'ed'ge '37 of the cover fits into the aperture 17 'ofthe'inovable 19 thus mounted is capable of blade and acts as a stop or limit for the movement of the blade.

It is essential in order to maintain the proper bearing pressure, I have found, to locate the front edge 37 of the cover sufficiently far enough back that the downward pressure exerted thereon will not cause the movable blade to exert too much pressure on the front tips of the stationary blade and --thas tip up the back "end of the stationary blade where there is necessarily a limited amount of play in the bearing to allow for smooth operation.

I preferably therefore locate the front edge 37 of the cover immediately back of a vertical line through the bearings 22 and 22 so that the pressure :exerted on the movable blade by means of this guide 37 tendsto hold the. stationary blade tight against its bearmgs.

From the above description, it is believed that the construction and advantages of this device will be clear to those skilled in this art. 1'

Having thus described, my invention, what I claim as new and desire. to secure by Letters Patent is: V

A hand clipper having'a frame, a stationary blade and a reciprocable blade, a guiding handle fixed to said frame, a movable blade operating handle pivoted to said frame and havingmeansengaging said movable blade, andgmeans slidably supporting said stationary blade foradjustment on said frame to vary its extension beyond the front edge of the movable blade, said last named means comprising a base plate having guides uponwhich the stationary blade rests and a lever interposed between saidbladeand base and having a finger piece at one side thereof for-moving the blade along the. guides, said lever being reversible to place the finger piece at either side for right or left hand operation. 1 r
